ASME/ASTM Boiler Tube & Pipe
ASME/ASTM Boiler Tube & Pipe:The high pressure boiler tubes are mainly applied on the super heaters, reheaters, water walls, economizers of the super critical and ultra super critical boilers. And are required to have high creep rupture strength, high anti-oxidation corrosion resistance, and stable microstructures.
The main code or grade of the ASME high pressure boiler tubes:
Mainly includes:
ASME/ASTM SA-192M, ASME/ASTM SA-209M
ASME/ASTM SA-210M: A210C
ASME/ASTM SA-213M T11、T12、 T22、T91
ASME/ASTM SA-106M:SA-106B、SA-106C
ASME/ASTM SA-335M:P11、P12、P22、P5、P9、P91、P92
The high pressure boiler tubes are often working in the condition with high pressure, high temperature and the interaction of the high temperature flue gas and vapor, which may lead to oxidation and corrosion on the tubes. So, the high pressure boiler tubes are required to have high creep rupture properties, high anti-oxidation corrosion and stable microstructure。
